Abstract

Purpose

The research paper comprehensively investigates the gear tooth deflection of standard thermoplastic gears with steel gear as the driver and driven companions. An accurate mapping of characteristic contact regions between the meshing gears was done, and the behaviour of the gear tooth in the premature and prolonged contact zones was studied.

Design/methodology/approach

The study employs the finite element method to conduct a quasi-static 2D analysis of meshing gear teeth. The finite element model was created in AutoCAD and analysed using the ANSYS 19.1 simulation package.

Findings

In the polymer-polymer gear combinations, premature and prolonged contact primarily occurs along the addendum radii of meshing gears, whereas a novel contact phenomenon was observed in the coast side for polymer-metal and metal-polymer combinations, exhibiting a path perpendicular to the standard drive side contact. As well, the deflection of the tooth alters the load distribution across the interlocking gears, leading to a decrement in the root stresses.

Originality/value

The Lewis bending equation demonstrates that bending stresses depend solely on the applied load and the geometry of the tooth. It does not consider the effects of deflection. However, the computational results showed that the gear tooth deflection caused by different gear pair combinations also affects the bending stresses. The contact stresses observed in the polymer-polymer gear combination were observed to be within the material’s proportional limit. However, when a steel gear is paired with a polymer gear, the contact stresses exceed the proportional limit due to coast side contact.

Abstract

Purpose

This study aims to explore the effects of internal financial technology (FinTech) integration within Jordanian banks on their performance metrics, specifically focusing on profitability, risk-taking and stock returns.

Design/methodology/approach

Using panel data analysis, this study investigates the financial performance of 13 listed commercial banks in Jordan over a decade, from 2010 to 2019, to examine the hypothesized impacts of bank FinTech developments. In addition, several robustness tests addressing potential issues of endogeneity and autocorrelation are conducted to enhance the reliability of the results.

Findings

The results reveal that the bank FinTech development significantly enhances bank profitability and inversely affects risk-taking levels, indicating a substantial and positive impact on financial performance and stability. However, the results suggest no significant evidence of the effect of bank FinTech development on stock return.

Practical implications

The findings advocate for Jordanian commercial banks to continue and expand their investment in FinTech innovations, highlighting the crucial role these technologies play in enhancing financial performance and reducing bank risks. Additionally, these findings suggest that regulatory bodies and policymakers should develop and enhance institutional and regulatory environments to support and guide the FinTech evolution within the banking sector.

Originality/value

This study sheds light on the relatively under-researched area of internal bank FinTech. It provides critical insights into how FinTech integration within banks contributes to their profitability and stability, offering another perspective that enriches the FinTech literature. This contribution is essential for devising future strategies, developing theoretical frameworks and informing policy decisions in the FinTech domain.

This article examines the relationship between the cash conversion cycle (CCC) and profitability in countries in the Middle East and North Africa (MENA) region.

Abstract

Purpose

This article examines the relationship between the cash conversion cycle (CCC) and profitability in countries in the Middle East and North Africa (MENA) region.

Design/methodology/approach

The authors used dynamic panel methodology to analyze a dataset consisting of 395 firms from nonfinancial sectors in the MENA countries from 2013 to 2018. The authors developed several models consisting of different measures of profitability, CCC and the components of CCC. The control variables were used in the models at different levels.

Findings

The results bring out a significantly positive relationship between the CCC and profitability. However, mixed results have been obtained for industry and country details. The quadratic model revealed an inverted U-shaped relationship and the presence of an optimal point of CCC. The robustness checks have confirmed the results of the main models.

Practical implications

The results of the study imply that corporate managers and policymakers ought to pay equal attention to the components of CCC when developing working capital policies and be aware of the optimal level of CCC.

Originality/value

This paper handles the endogeneity problem that is inherent in the relationship. It investigates and confirms the nonlinear characteristics of the relationship. To the best of the authors' knowledge, this study is the first to use dynamic panel models to examine the CCC and its relationship with profitability in the MENA context.

Abstract

Purpose

This article investigated whether the executives' compensation and corporate governance attributes are aligned with stakeholders' demands for higher corporate voluntary disclosures. Moreover, the study also examined the moderating role of the auditor's reputation in the direction of association among executive compensation, corporate governance attributes, and voluntary disclosures.

Design/methodology/approach

The study used a sample of S&P BSE index constituents' 90 Indian firms for 2017–2019. The voluntary disclosure scores were fetched from the India Disclosure Index Report published by FTI Consulting. This analysis was carried out in two parts by applying four panel-data regression models in the agency and signalling theories framework. First, the study examined the association between executive compensation, board strength, composition, gender diversity, and voluntary disclosures. Second, the article investigated the moderating role of the “Big 4” in the direction of association among executive compensation, corporate governance attributes, and voluntary disclosures.

Findings

The willingness of executives to share private information with stakeholders depends on the compensation they receive from their employer. The higher compensation paid to executives leads to a higher “tone from the top,” which is better aligned with stakeholder interests. Further, the research also found that bigger board sizes, a higher proportion of independent and woman directors (indicators of good governance), and an auditor's reputation are associated with increased voluntary disclosure.

Research limitations/implications

The findings showed that the executives' compensation and corporate governance attributes are aligned with stakeholders' demand for higher voluntary information from firms. Moreover, the study also found that the “Big 4” play a moderating role in this direction. The choice of a reputed auditor indicates the firms' long-term positive future perspectives, which strengthens investor confidence in the financial market.

Practical implications

The study suggests that fair executive compensation can address the agency problem.

Originality/value

This research furnishes managers and different stakeholders with significant implications of executives' compensation, corporate governance, and auditor's reputation in the best interests of a firm through reducing potential risks of information asymmetry.

Abstract

Purpose

This study aims to explore the internationalization of multinational enterprises (MNEs) from China and aims to examine the relationship between Chinese MNEs’ duration of internationalization and export intensity, and the contingent roles of the home country government.

Design/methodology/approach

By extending the springboard theory with institutional and cost-benefit analyses, the authors elaborate a two-phase framework of internationalization to explain how Chinese MNEs develop their international business under the influences of the home country government. Furthermore, the authors apply the Heckman two-stage method based on a panel data set of 19,994 firm-year observations of Chinese listed firms in 2008–2018 to test the hypotheses.

Findings

The research findings demonstrate an inverted U-shape relationship between the duration of internationalization and the export intensity of MNEs from China. The export intensity of MNEs from China increases during the initial phase of internationalization, and decreases during the subsequent. A further study reveals that the inverted U-shape of Chinese non-SOEs is steeper than that of SOEs, and this moderating effect is more salient after the Belt and Road Initiative. These results highlight the influence of the home government through state ownership and policies on the inverted U-shaped relationship.

Originality/value

This study helps to refine the understanding of Chinese MNEs’ global expansion by addressing time as an explicit dimension and revealing the mechanism of state ownership and the home country governmental policy in the dynamic internationalization process.

Abstract

Purpose

This paper aims to construct a novel measure of firms’ perceived degree of economic policy uncertainty (EPU) and to examine its impact on imitative innovation.

Design/methodology/approach

This paper uses text mining methods to extract valid information for management discussion and analysis from the annual reports of Chinese A-share-listed companies from 2009 to 2021.

Findings

The empirical findings demonstrate that firms that perceive higher uncertainty in economic policies promote increased imitative innovation behaviour. In addition, when uncertainty is high, overly optimistic managers can reduce the imitative innovation of the firm to other firms.

Originality/value

The paper uses some of the more recent textual analysis techniques in the field of innovation to measure listed firms' perceptions of external EPU and to examine the impact of uncertainty on imitative innovation. Such research enriches the literature on innovation and fills some gaps.

Abstract

Purpose

This study aims to improve the automatic leveling performance of tractor body in hilly and mountainous areas by designing a kind of controllable and adaptive leveling mechanism of tractor body.

Design/methodology/approach

The mechanism is mainly composed of longitudinal slope leveling mechanism, transverse slope leveling mechanism and control components. According to the tractor body attitude in operation, the longitudinal slope leveling and lateral slope leveling can coordinate to realize the adaptive adjustment of tractor body. For this mechanism, the support mode of the linear three-point support and plane positioning combining is designed, and the leveling method of electromechanical combination is designed. The servo motor controls the longitudinal slope leveling mechanism through the reducer with self-locking function to realize the longitudinal leveling, and the servo driver controls the expansion and contraction of electric cylinder to realize lateral leveling. The designed mode can realize the relative independence and coordination of leveling in different directions.

Findings

The performance test results of the leveling mechanism are shown: the mechanism can work normally; the leveling accuracy can reach within 1°; and the leveling accuracy and stability can meet the design requirements. The leveling accuracy and stability of longitudinal slope are higher than that of lateral slope, and the coordination leveling effect of longitudinal slope and lateral slope is better than that of the independent leveling.

Originality/value

This study provides a technical reference for the design of leveling device of agricultural machines and tools in hilly and mountainous areas.

Abstract

Purpose

Endurance time is an important factor limiting the progress of flapping-wing aircraft. In this study, this paper developed a prototype of a double-wing flapping-wing micro air vehicle (FMAV) that mimics insect-scale flapping wing for flight. Besides, novel methods for optimal selection of motor, wing length and battery to achieve prolonged endurance are proposed. The purpose of this study is increasing the flight time of double-wing FMAV by optimizing the flapping mechanism, wings, power sources, and energy sources.

Design/methodology/approach

The 20.4 g FMAV prototype with wingspan of 21.5 cm used an incomplete gear flapping wing mechanism. The motor parameters related to the lift-to-power ratio of the prototype were first identified and analyzed, then theoretical analysis was conducted to analyze the impact of wing length and flapping frequency on the lift-to-power ratio, followed by practical testing to validate the theoretical findings. After that, analysis and testing examined the impact of battery energy density and efficiency on endurance. Finally, the prototype’s endurance duration was calculated and tested.

Findings

The incomplete gear facilitated 180° symmetric flapping. The motor torque constant showed a positive correlation with the prototype’s lift-to-power ratio. It was also found that the prototype achieved the best lift-to-power ratio when using 100 mm wings.

Originality/value

A gear-driven flapping mechanism was designed, capable of smoothly achieving 180° symmetric flapping. Besides, factors affecting long-duration flight – motor, wings and battery – were identified and a theoretical flight duration analysis method was developed. The experimental result proves that the FMAV could achieve the longest hovering time of 705 s, outperforming other existing research on double-wing FMAV for improving endurance.

Abstract

Purpose

Studies on sustainable finance examine how it is interrelated with economic, social, governance and environmental issues. Using financial data on publicly traded firms in Indonesia, this study aims to explore the interplay between the cost of capital, firm performance and the COVID-19 pandemic.

Design/methodology/approach

This study uses firm-level data sets of publicly listed firms from 2012 to 2021. The regression analysis reported in the study includes the Driscoll–Kraay estimator, propensity score matching model and fixed-effects regression.

Findings

The study revealed three significant findings. First, on average, non-environmental, social and governance (ESG) companies’ cost of capital is lower than that of ESG firms. Second, ROE in ESG enterprises is significantly impacted by capital costs. Third, the cost of capital has a negative impact on the market value (Tobin’s q) of non-ESG firms. The study specifically shows that after accounting for the pandemic, ESG firms did not benefit during the troubled COVID-19 crisis after controlling for the pandemic dummy years of 2020 and 2021. These results indicate that the adoption of green or sustainable finance is still in its infancy and that the sector requires more time to establish an enabling environment.

Research limitations/implications

This study benefits from capital structure and ESG theories. It supports the argument that the debt utilization ratio is still relevant to a company’s value because it affects its financial performance. Moreover, adopting ESG principles helps businesses survive crises. Thus, the analysis confirms the superiority of ESG-based firms.

Practical implications

This study draws two conclusions. First, the results could be a reference for academics and practitioners to understand the effect of pandemic-related crises on a firm’s capital structure and performance. In terms of survival during a crisis, such as the COVID-19 pandemic, this study demonstrates how firms with strong ESG may perform differently than those without ESG. Second, this study supports the need for an empirical study and examination of the development of sustainable finance in the country while considering setbacks.

Social implications

The results should be of interest to policymakers who focus on the ESG market and academics conducting ESG-related research on emerging markets.

Originality/value

This study contributes to the literature by establishing empirical evidence on the relationship between the cost of capital and firm performance of ESG- and non-ESG-rated enterprises in the Indonesian setting while controlling for the impact of the pandemic.

Abstract

Purpose

Emerging market multinational companies have been vigorous in pursuing inorganic growth through cross-border acquisitions (CBAs). The fundamental studies till now have portrayed that rapid internationalization through CBAs tends to create value for these emerging market firms (EMFs) in the short term. However, there is an ambiguity about whether these firms endure better performance in the long term. The purpose of this study is to assess the long-term (ex-post) financial and operating performance of EMFs involved in overseas acquisitions before the COVID-19 pandemic hit the world economy.

Design/methodology/approach

CBAs completed by Indian and Chinese companies constitute the sample of the study. The performance has been analysed during the pre-COVID period spanning 17 years from 2001 to 2017. A comprehensive set of 14 financial ratios has been used to represent change (improvement/decline) in enterprises’ post-acquisition operating performance; these ratios have been divided into four broad groups: profitability, efficiency, solvency and liquidity ratios.

Findings

The performance of Indian companies has deteriorated significantly after the acquisition. However, there has been no change (deterioration/improvement), subsequent to CBAs, in the profitability of Chinese firms.

Practical implications

The findings of the study support that firms from emerging economies exploit CBAs as a “springboard” to obtain strategic assets including intangible resources and brands rather than to achieve synergies through economies of scale and scope. Apparently, outbound acquisitions by emerging economy firms are not driven by cost-reduction or revenue-generation activities.

Originality/value

None of the studies, to the best knowledge of the authors, has carried out performance analysis using a comprehensive set of financial ratios. The comparative study of two emerging economies is another valuable addition to the existing literature. The study holds the potential to serve as the benchmark to assess the performance of CBAs executed after COVID-19.
